Convert byte[] array to File using Java In order to convert a byte array to a file, we will be using a method named the getBytes() method of String class. Implementation: Convert a String into a byte array and write it in a file.
A byte array is an array of bytes (tautology FTW!). You could use a byte array to store a collection of binary data, for example, the contents of a file. The downside to this is that the entire file contents must be loaded into memory.
You can simply iterate the byte array and print the byte using System. out. println() method.
Byte class is a wrapper class for the primitive type byte which contains several methods to effectively deal with a byte value like converting it to a string representation, and vice-versa. An object of Byte class can hold a single byte value. Byte class offers four constants in the form of Fields.
try (FileOutputStream fileOuputStream = new FileOutputStream("filename")){
fileOuputStream.write(byteArray);
}
Try this:
Files.write(Paths.get("filename"), bytes);
